Requirements

A bachelor's degree in Electrical or Computer Engineering and 5+ years of relevant industry experience are required.
Hands-on experience with silicon validation, characterization, or post-silicon debug of mixed-signal integrated circuits is required.
Understanding of mixed-signal blocks such as analog-to-digital converters, digital-to-analog converters, phase-locked loops, amplifiers, regulators, and sensors is required.
Experience developing automated test software is required; Python is preferred.
Experience using laboratory instrumentation is required; familiarity with PXI-based systems is a plus.
Effective data-analysis and problem-solving skills are required.
Effective communication skills and experience working across engineering teams are required.
Candidates must be able to access technical data without requiring an export license; the employer cannot sponsor or obtain export licenses for this role.

Responsibilities

Perform hands-on silicon validation and characterization from first silicon through production release, contributing to test plans and coverage for analog, digital, and mixed-signal blocks.
Build and improve automated laboratory setups and test software using Python, PXI systems, and benchtop or laboratory instrumentation.
Design validation boards and review schematics and layouts; measure and analyze performance, margins, robustness, and corner conditions.
Partner across engineering teams to debug silicon issues, find root causes, and connect validation results to production test limits and guard bands.
Strengthen validation methods, documentation, and laboratory efficiency; present findings and provide technical guidance to junior engineers.

Desired Qualifications

Experience validating audio or power-management integrated circuits.
Experience working with digital interfaces such as I2C, SPI, I2S, TDM, or SPMI.
Experience using embedded firmware or laboratory-automation platforms.
Experience correlating validation results with production test.
Experience providing technical leadership or mentoring junior engineers.
